Things got messy last night on "The Tonight Show Starring Jimmy Fallon." Sandra Bullock and the late night host attempted to feed each other ice cream using mannequin arms on a fake soap opera called "Jacob's Patience."

Bullock and Fallon discussed their time together on the Canadian soap opera, where the "Blind Side" actress played an ice cream shop owner and the "Tonight Show" host was her first ever customer. Bullock even dared to call the show "amazing."

The actress was shocked to hear that Fallon thought she was difficult to work with onset due to her refusal to "use her own arms."

Bullock explained that at the time she was a ring pop hand model and her hands were insured for "like $50,000 a piece."

"No matter what the deal was you refused to use your arms, you used fake arms, you used mannequin arms during all of your scenes," Fallon told the actress. "Then, the director to make you feel more comfortable made all of us act with mannequin arms. I have to say it made things pretty inconvenient."

"I don't think anyone even noticed," Bullock said.

The fake soap was part of Fallon's "Real People, Fake Arms" series which has previously featured Miley Cyrus and Seth Rogan.
